One electrician charges a $50 service call fee plus $25 per hour for labor. Another electrician charges a $35 service call fee plus $27.50 per
hour for labor. How long would a job take if the total cost for each electrician is the same?
A.5 hours
B.6hours
C.7 hours
D.8 hours

Answers

Answer:

c. 6 hour

Step-by-step explanation:

time = t

25t + 50 = 27.50t + 35

solve for t : 25t + 50 = 27.5t +35

27.5t + 35 = (55t) /2 + 35 : 25t + 50 = (55t) /2 + 35

subtract (55t) /2 + 50 from bot side : -(5t) /2 = -15

multiply both side by -2/5: t = 6 hours

Step-by-step explanation:

A moving company’s moving rates can be represented by the function f(x) = 3x + 400, where x is the number of miles for the move.

Another moving company’s rates can be represented by the function g(x) = 5x + 200.

Which function represents the difference between the moving companies' rates, h(x) = f(x) – g(x)?

A) h(x) = 2x + 200
B) h(x) = –2x + 200
C) h(x) = 5x – 200
D) h(x) = 5x + 600

Answers

Answer:

B) h(x) = –2x + 200

Step-by-step explanation:

f(x) = 3x + 400

g(x) = 5x + 200

f(x) - g(x) = 3x + 400 - (5x + 200) = -2x + 200

Answers

Answer:

-10, -1, 5

Step-by-step explanation:

To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....

x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...

x = -10

x-5=0

then repeat (add 5 to both sides) (and subtract 1 from both sides) ...

x -5 = 0 to x = 5

x + 1 = 0 to x = -1
